主 题：Surface water resources Climate changes Response Jilin China
摘 要：[Objective] The response of surface water resources on climate changes was studied.[Method] By dint of monthly average temperature and precipitation in 45 meteorological stations in Jilin Province from 1960 to 2000,monthly runoff in 56 hydrological stations in Songhuajiang and Liaohe region,the surface runoff change and the response of surface water resources to climate change in 41 years were expounded.[Result] The runoff of Songliao region was limited during 1960s and *** began to increase slowly in the early *** 1990s,there were distinct fluctuation of annual runoff and it was decreasing in *** analysis suggested that the runoff of Songliao region was decreasing gradually from south to the *** central gradient was small and runoff was evenly *** test result showed that the annual runoff in Songliao region had large fluctuation before 1980s and after *** response of surface runoff on climate and precipitation changes in Jilin Province was distinct and had strong relevance as well as certain *** on the analysis of the relation of rivers runoff and meteorological elements changes,statistics forecast model between river surface runoff and meteorological elements was *** prediction value and measured value had good *** corresponding river surface runoff changes can be assessed based on the changes of meteorological elements.[Conclusion] The study provided theoretical basis for the development and utilization of surface water resources in Jilin.
